Isomorphous — Definition, Formula, Properties & Uses | AllChemicals | AllChemicals

What is Isomorphous?

Isomorphous substances are those that crystallize in the same or very similar crystal structures and have similar chemical formulas, often because they contain ions or atoms of similar size and charge. Examples include the alums (e.g., KAl(SO₄)₂·12H₂O and KCr(SO₄)₂·12H₂O) and the calcite group of carbonates (CaCO₃, MnCO₃, FeCO₃). Isomorphous compounds can often form solid solutions (mixed crystals) with each other in any proportion.
